Application filed October 2, 1920. Serial No. 414,239.

State of California, have invented certain new and useful Improvements in'Rabbeting Machines, of which the following is a specification, reference being had to the accompanying drawings. i

, This invention relates to improvements in rabbeting-machines and more particularly to machines of this character adapted for the formation of side and end boards for bee hives;

An important object of the invention is to provide means whereby a board, which has been previously cut to required rectangular dimensions, may be simultaneously pro-.

vided with the usual rabbet by means of which thehoney boards are positioned with in the hive and with the handhold by means of which the hive is handled. v A further object of the invention is t provide means whereby in manufacturing end boards similar in character'to those previously designated, withthe exception of the fact that they are provided in thell" grooves which are sides with shipl'ap utilized in assemblingthe hive, this may be constructedin one continuous operation and without handlingby the operator of the .machine other than the "handling neces sary to place the same in the machine and to withdraw the completed article therefrom.

A further object of the invention is' to provide a novel transferring mechanism whereby the end boards maybe transferred from one table performing one operation thereon to a second table" performing a sec ond operation thereon.

A further object provide means whereby the above'opera tions may be carried out eiiiciently and continuously and withfa'minimum amount of attention from the operator, v

Other objects and'advantages of the invent-iori will become apparent throughout the course of the followingdescription;-

Referring now more particularly t'o the drawings, wherein for theflpurpose 0f lustration is shown a preferred embodiment of'my invention and wherein like reference" characters designate like parts throughout? Figure l is a-plan' view of 'appa'ratus constructed' in accordance with my invention.

Figure 7 is a front elevation of the track mechanism employed in transferring the boards from one table to another.

Figure'8 is a fragmentary sectional view showing the method of returning the tracks to normal position, and v Figure 9 is afragmentary sectional view illustrating-the manner of tripping the tracks to release the boards in the transferring operation. Y

In the construction of my invention I preferablyemploy a base 10 having extend- .ing upwardly therefrom supporting legs 11 provided at their upper ends with a-table 12. -This table 12 has mounted for rotation at the ends thereof horizontal transversely extending shafts. 13 and 141. Each oft-he shaft 13 and 14 is provided with a sprocket 15 arranged approximately centrally-of the table and a sprocket 16--arranged at' one side ofzthe table, these sprockets andlG being" alined. The sprocketswlfi are conne'cted by the'sprocket. chain 17-and the sprocket ldbythe chain 18. "The chainl? is provided at spaced intervals with carrier lugs 19 projecting upwardly from the links thereof. v

Mounted adjacent therear or; entrance end ,of'the machine, upon the tablelQ, .isa magazine 20 adapted to receive boards 21 which have previously 'bcenfcut to the proper shape and length- .This magazine-is provided in its forward end, at the bottom thereof, with an opening-20 of suflicient size to allow removal 'of the boards therey from: The carrier lugs l9'are of the same height as, or of slightly less height than, the thickness of 1 the boards 21 and are space dapart upon the sprocket chain a distance slightlygreater than the length of theseboardsQ Y I ldountedadjacent one side of the table is a longitudinal plate 22-forming a guide. A

tension guide 23 is providedshaving its real:

end 24 curved outwardly to permit ready reception of the ends'of-the board. This plate is tensioned by means of springs 25 extend ing intermediate the plates and lugs 26 extending upwardly from the face of the table 12. It will be seen that when the shaft 13 is rotated the carrier lugs 19 passing through the magazine 20 will engagetheends of the boards 21 causing the boards to pass out-- wardly from the magazine through the opening 20 The spring guide 23 will open sufliciently to permit the entrance of the board due to the curved end 24 thereof and will hold theboard firmly against the guide plate 22. V Pivotally', connected to the vforward end of the magazine, as at 27 is a bar 28,'having adjustably vmounted upon the free end thereof a counterweight 29; This bar is provided upon itsunder surface with-spring fingers 30 curved in the direction of movement of 7 7 the boards 21 in leavingv'the magazine and is for the purpose of holding thefboards firmly upon the table. It will be-noted'that the pressure exerted in holding the boards upon the table maybe readily adjusted by means ofthe counterweight 29.

A shaft 31 ismounted in suitable journals carriedby the table 12 and extending thereabove. This shaft extends'transversely of the table above and is provided" upon its outer end with a small pulley 32 and has its inner end or that end-thereof disposed above the table with the cutter head 83, this cutter head being so positioned that the outer face thereof ispositioned adjacent the guide plate 22.

- mounted in iournals carried by the legs 11 and is provided-with a large pulley 35 which is connected with thepulley 32-fof the shaft 31 bymeans' ofrthe belt 36. The shaft 34 is likewise provided with a secondpulley37 i e which is relatively small and which is consmall pulley 42 upon a shaft '43, rotatably" nected with a relatively large pulley 38 secured to the count'ershaft 39 by'means of the cross belt 40. i

The shaft 13 is'provided with a relatively large pulley 41 which is connected with a supported by the legs '11, bymeans of a belt 44. The shaft 43 is likewise provided with a secondpulley 45 which is relatively large and which is connected'with a small pulley 46 mounted on the shaft 49 by means of the cross belt 47. Y v I "Rotatably mountedbeneath the table 12 in any suitable manner, is a -shaft48" which carries the pulley 49 which is connected, by

means of a'belt 50,.with the relativelylarge.

pulley 51 secured to the, counter shaft 39.;

Mounted 'securelyon the shaft 48 is asecond pulley 52. Mounted for oscillation about the shaft 48 is a yoke 53, embodyingspaced arms if 54 extendingon opposite sides of'the pulley 52and suitably apertured to receive the shaft A shaft 34 is rotatably- The sprocket chain 18 which connects the sprocket 16 is provided at spaced intervals withcams 59 projecting upwardly from the links thereof. These cams are spaced :apart on the sprocket chain a distance similar "to the distance between the carrierlugs 19 and are staggered with. relation thereto, being arranged, approximately centrally with relation to the plates 19. As the sprocket chains 17 and 18 are of the same length and r are driven-by thesame source these chains will'constantly remainin fixed relative position.'.

Mounted in a bracket 60 carried bythe table 12 adjacent the chain 18 is ashaft61 having" secured thereto a relatively larger;-

sprocket gear 62. Thisshaft has likewise secured thereto a' radial arm 62 the end of which engages the sprocket chain-18 andis adapted to be shiftedby the cams 59thereof.

- Botatably mounted beneath the table 12 extending transversely thereof is a shaft 63 having secured to the end thereof adjacent the sprocket 62 a relatively small sprocket 64 connected with the sprocket 62 by means of cause a corresponding oscillation of the sprocket gear 62, which oscillatlon is trans:

a sprocket .chain 65. It; will be-seen that. 1- elevation of the arms 62 by the cams 59 will ioo mitted to the sprocket" gear 64 bythechain 65;. Mountedupon-the opposite end oflthe shaft 63 and secured against rotation with relation thereto isa' radialzarm 66. This arm hasvsecured theretofor adjustment lon-s gitudinally thereof asat 67, alink- 6,8,:which is pivotally connected at its lower end toaq stud 69 on the. free end of the yoke 53. i The pear. 7

My device, in so-far as described, is-that portion of the apparatus necessary for form:

ing hand hold openings and top. rabbet grooves in the side boards of bee hives, or

of. any equivalent box like structures The operation thereof-is as follows: 7 v

Power being supplied to the shaft, 39v and the magazine 20 being'provided with ready I shaft 56 carried thereby is provided witha cutter head 70 for a purpose presently to ap cut-"boards 21, the" rotation of the shaft 13 causes the sprocket chains 17 and 18 to travel longitudinally towar'dthe front or discharge end of the machine and as-each carrier lug 19 passes below the'magazine 20' it engages aq-looard 2l-"drawing the same outwardly throughthe. opening20 As the looar dfis I 'movedoutwardly and at the'tirne when'the board is correctly positioned to form the mediately beneath the for-wardend of the magazine20 in order that the upward thrust of'thecutter head 70 may not vertically displace the boards and resnlt in-a miscut,v Continuing, the board is pushed by carrier plate 19 beneath'the cutter head 33 on the shaft31 which'is revolving at a relatively high rate of speed in the direction opposite to the direction of movement of the board,

with relation to" the engaging'portions of the cutter head and board. At this point any tendency to vertical displacement which may be caused by the engagement of the cutter portions of the cutter head 33 in the end grain of the board is effectually counteracted by the'spring' fingers 30." g

' Arrange'd'transversely of the forward or discharge end of the table 12 is 'a second table. This table is arranged slightly below the level of the table 12 and is provided at each endthereof with'a shaft 73 embodying sprockets 73 connected by a sprocket chain 74. These chains are connected at intervals by carrierp'lates 75. Rotatably mounted above the table72 is a shaft 76' embodying spaced cutter heads 77 which are 'adjust- 1 ably mounted thereon. This shaft is connected with the shaftBQ as a t- 76?, to be driven thereby;

Arranged at'opposite sides of the table 72 in alinemen-t with the table 12 are supports 78 and 79' arranged ingpairsas shown, the supports 78being secured to the table '12 and the supports 79 to the table 72'. Each pairfof supports "has pivotally mounted there-between as at 80, a track '8Q pref-erably formedof'angle iron or 'the like. 'These tracksare counterweighted as at 81in order thatithey may normally maintain a vertical position, 1 pivotal movement thereof being limited by stops 82 carried by the supports 78 when the horizontally disposed portions of the tracks are in proper alinement with the table 12. These tracks are arranged at the same level as, or slightly below the level of the table 12 and are adapted'to receive the boards therefrom as they are discharged from the forward end of this table. The tracks are held in elevated position by means of latches 83 pivotally mounted upon the supports 78'and embodying a nose piece 84 which engages the vertical portion of the I 66' track. I 1

support 781b6l OW'tl1B lever and'a stop 'lug arranged above the lever to limit the upwardmovement thereof and a spring 88 extending intermediate the lug 86 and the lever 85. A link 89 is pivotally connected to the lever 85 intermediate its ends-and engages the free end of the latch 88at its opposite end. Adjustment of the free end of the-latch 83 upon the link 89 is obtained by means of an adjusting nut 90 and spring 90.

The operation of this portion of my device a is as follows: a

The boards pr'ovided'upon the table 12 with a rabbet 71 and hand holds 71 are discharged upon the tracks80 by the chain conveying mechanism 17. The carrier lug 19 which projected thefboard by engagement therewith after delivery of the board upon the tracks 8O trips the levers releasing the latches'83. The counterweight 81 is of such size that the boards 21 when placed upon the tracks will 'overbalance the same when the latches are released andicause the tracks to rotate, permitting the boards to drop upon the table 72. The carrier'plates 75 of the table 72 are so spaced that the release of the board occurs just when the board'is positioned intermediate two of these plates; The board is pushed by the carrier plate-7 5 intermediate the guides 91'and 91?. Theguide' 91 "is stationaryand the' guide 91 is 'adjust-j able and serves to position the board for en j gagement by" the cutter heads 77. As the board passes beneath these cutter heads it is provided upontheopposite surface thereof from the hand holds '71 a-ndin the edges i I thereof, ang'ularly disposed to the edge provi'ded" with the groove 71 with rabbet grooves 72*. Each board is carried by the carrier bars 75 to the end of'the table where a' suitable-receptacle (not shown) may be provided.

It will-be understood that the various driving mechanisms employed-in theopera= particular construction or arrangement of the various parts herein shown but may make any changes which do not depart from the spirit of the invention or the scope of the sub-joined claims.
